This put a smile on my face. I don't know why. I don't have kids. But I still find it amusing.
By the way... if you're already on the 8th kid, why are you asking us if you should've gotten a dog instead? Do you have any dogs? If not, then in terms of dogs versus babies you sound like you've got plenty of brand loyalty to justify your decision. XD
They're little bundles of chaos... I caught my 5 year old punching a knitting needle into our sofa. My first question was, "Why would he DO that?" There really is no answer to that question--it's why kids always tell you, "I don't know" when you ask them that.
The second (and probably more confusing) question was, "Why do we even HAVE a knitting needle?"
